13. Using data from 50 workers, a researcher estimates Wage =
Bo+B,Education + B₂Experience + B3Age+e, where Wage
is the hourly wage rate and Education, Experience, and Age
are the years of higher education, the years of experience, and
the age of the worker, respectively. A portion of the regression
results is shown in the following table. ni ogolloo bash

1. If a firm spends more on advertising, is it likely to increase
sales? Data on annual sales (in $100,000s) and advertising
expenditures (in $10,000s) were collected for 20 firms in order
to estimate the model Sales = Po + B₁Advertising + ε. A portion
